SHUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 321,396, dated June 30, 1885.

Application filed February 4, 1885. (No model.)

To aZZ whom it may concern:

Be it known that I, GEORGE W. SrovE-R, a citizen of the United States, residing at Laurelton, in the county of Union and State of Pennsylvania, have invented certain new and useful Improvements in Shutter-Vi orkers, of which the following is a specification, reference being had therein to the accompanying drawings.

Figure 1 is a horizontal section ofa windowcasing, showing my invention in top view, the two blinds being provided with shutter-workcrs of slightly different construction. Fig. 2 is an elevation from the outside, the blinds being open. Fig. 8 is a horizontal section on the line 3 3, Fig. 2, looking upward. Fig. 4 is a section of one of the adjustable shutteroperating levers. Fig. 5 is a view of a modified form of shutter-worker.

In the drawings, A represents the side walls of the casing; B, the blinds hinged thereto; 0, the outer sill, and D the inside window-sill.

This invention relates to that class of shutter-workers employing levers which swing the blinds, and which have handles situated upon the inside of the window, so that the blinds may be operated without necessitating the raising of the sash; and it consists in making the levers and links connected with the blind extensible to permit them to be adjusted to any thickness of wall; and it also consists in various improvements in the details of con struction, as will be hereinafter pointed out.

I will first describe the construction shown at the right-hand side of Fig. 1.

E is a lever lying upon the top of sill C and connected at its inner end to a vertical post, F, which serves as its pivot. The post F extends upwardly through sill D a short distance back from its outer edge, and carries at its upper end an arm, G, provided with a handle, g. The arm G is preferably formed of spring metal and bears downwardly at its outer end, where it is provided upon the under side with a small pin, adapted to be seated in apertures h in the plate H attached to the upper face of the window-sill. By lifting upwardly upon the handle, the lever will be sprung slightly and the pin withdrawn from apertures h, thus permitting the post to be rocked and lever E to be moved.

I is a link attached at one end to the outer end of lever E, and having an upwardly-projecting-pin, i, at its opposite end adapted to be seated in a socket in the lower edge of the shutter. This socket is provided with a metallic lining or bushing to prevent wear.

The lower edge of the shutter is rabbeted upon the inner side, thus forming a narrow strip or facing-piece, b, which, when the shutter is closed, effectually hides the shutterworking devices, and also forms a tight joint with the sill O. The sill D is cut away, form ing a chamber, (1, in which lies the lever E and link I. when the blinds are closed.

I have found it very desirable to make the shutter-operating lever extensible between its pivot and its connection with the link I, or with the shutter when the link is not employed, as thereby my device may be applied to houses wherein the walls vary considerably in thickness; and in order to permit this the lever Eis formed of two thin plates of metal, 6 e, unit-ed together by a pin or rivet, J, one of the plates being provided with a series of apertures, 6, whereby the parts may be adjusted relatively to each other and the lever lengthened or shortened.

When the length of the lever is changed, a corresponding change is necessary in the link I to enable the parts to properly fold together within chamber cl, and I have shown the link formed in two parts, i i, connected by pin or rivet I, and adapted to move relatively to each other.

By referring to Fig. 4 it will be seen that each strip or plate 0 e is provided upon one edge with a flange, 6 Thus, as shown, the lower part, c, to which is pivoted the link I, is provided upon its right-hand edge with an upwardlyprojecting flange, which overlaps the right-hand edge of plate c, while plate 6, which is attached to post F, has upon its lefthand edge a flange projecting oppositely from that on plate 6. These flanges serve to keep the two plates from twisting relatively to each other upon the pin or rivet J, insure that the lever shall be sufficiently rigid, and also give to the lever a neat appearance, the two flanges serving to hide the joint between the two plates upon the opposite edges, respectively. The plates t i, forming link I, are also pro- ICO vided with flanges 71 similar to those carried by the plates 6 e, and operating in the same manner.

The plate 0, to which link I is pivoted, ex tends beyond the end of plate 6, to allow free movement of the plate i of the link when the parts are shifted from the position occupied when the blind is open to that occupied when it is closed. The outer flanged end of the plate e is curved, as at e, in order to better hide the pivotal connection between the link I and the lever E, and to give a neat unbroken appearance to the shutter-working mechanism when the blind is open and the link and lever are exposed to view.

The construction of devices shown upon the left-hand side of Fig. 1 is substantially similar to that above described, but differs in having the lever E of substantially S shape and pivoted at F to the sill 0 below the window-sill. The inner shorter end, E, of lever E is provided with an upwardly-projecting arm, G, carrying the'handpiecc g at the upper end above the window-sill. The sill D and plate H are provided with a circular slot, h, to permit the movement of arm G. The plate H is provided with a downwardly-extending portion, h, adapted to cover the outer face of sill D and hide any disfigurations which might have been caused by forming the slot h in the sill and the chamber (2, in which the arm E of the lever works.

I do not wish to be limited to the exact construction shown and described herein, as I might use that portion of my invention which pertains to making the lever extensible in combination with one of that class ofshutterworkers in which a swinging lever is employed, one end of which engages directly with the shutter and the other end carries the handle, as shown in Fig. 5; nor do I wish to be confined to the use of an extensible link when an extensible lever is employed, as links of different lengths might be used when the length of the lever was changed.

I am aware that it is old to make a shutteroperating device consisting of a bell-crank lever pivoted outside the wall of the apartment and on the same vertical line as that upon which is hinged the shutter, and having one end connected fixedly to the shutter and the other end secured to an extensible rod which passes through the wall to the inside of the apartment, this rod being operated by another bell-crank lever, such a device being shown in a patent to one Rogers, dated August 31, 1858, No. 21,368, and hence I do not claim such as my invention; but an arrangement of this character differs very materially from mine, the shutter operating lever in such earlier construction not being extensible, the extensible rod there shown serving only as a handle or connection by which the shutter-operating lever is worked from the inside of the apartment.

In order to permit the bell-crank and the shutter to oscillate about glifferent centers, as

in my construction, I prefer to use one of the two arrangements shown that there may be the necessary freedom of movement-that is, either a link between the lever and the shutter, as in Figs. 1, 2, and 3, or a rail or rod upon which travels the outer end of the leverboth these arrangements permitting the outer end of the lever to approach and recede from the vertical line of hinging of the shutter. This enables me to make the shutteroperating lever extensible between its pivot and the shutter, which would not be possible were the lever connected fixedly to the shutter, and also allows the lever to be mounted within thewall of the apartment, which is not possible where the shutter and its operatinglever are hinged on the same vertical line.

I am aware that a shutter-working lever has been provided at its inner end with a knob having a downwardly-projecting eccentrically-arranged pin, which engages with a notched rack to lock the lever in various positions, and thereby adjust the distance to which the blind shall be opened, such knob and pin being provided with a spring which forces the pin into engagement with the notched rack, and I do not claim such a device.

WVhat I claim is 1. In a shutter-worker, the combination of a shutter, a lever pivoted on a line inside that on which the shutter is hinged and extensible between its pivot and the shutter, and a haudle by which the lever is operated, substantially as set forth.

2. In a shutter-worker, the combination of a shutter, a lever pivoted on a line inside that on which the shutter is hinged and extensible between its pivot and the shutter, a link connecting the lever with the shutter, and a handle by which the lever is operated, substantially as set forth.
